The CGW 42775 is a 7 inch diameter zirconia flap disc designed for aggressive metal finishing on steel. It uses a zirconia alumina grain on a durable poly/cotton backing, which balances grinding performance with a smoother finish. The zirconia concentration in the grain provides high stock removal, helping to accelerate material removal in heavy-duty applications while the backing helps maintain disc integrity during extended use. An active grinding aid is included to promote cooler cutting under light pressure, potentially reducing heat buildup and workpiece discoloration during grinding.
